Over on Evolt.org today, there's a new tutorial combining two great tastes that taste great together - Ajax and PHP - to create an online calendar system quick and easy.

There are many web calendars in the market but some of them are quite complicated. If we are not able to understand the code, it becomes harder for us to customize the calendar to fit into our existing application. As such, we need to create a calendar that can plug itself into any system seamlessly without problems.

They show the creation of a calendar that can be used by including one line into the app and integrates easily into whatever style the website might be using. They give the code for building the calendar and to add dates to it on the server-side with PHP. The Ajax comes in when they make a call to the script in the background, requesting the next/previous month's output and pushing it into a local div.
